GENERAL PRODUCT DESCRIPTION
The LF115-8A is the perfect low frequency companion for the
DS912-8A. Equipped with a 15 inch / 380 mm low frequency
speaker housed in a durable 18 mm / 13-Ply Poplar cabinet, the
LF115-8A offers affordable system expansion in an easy-to-install
package. The LF115-8A will complement the low frequency
performance in Auditorium and House of Worship systems.
Altec Lansing's high performance model 4156-8A woofer is a 15
inch / 380 mm speaker with a robust corrosion-resistant die-cast
frame and a weather-resistant cone for maximum durability in all
environments.
The unique on-board crossover network provides simplistic add-
on operation without the need for an additional power amplifier
channel or the costs associated with additional amplification and
an active crossover. The charcoal grey or white painted cabinet
blends into most backgrounds, or it can be easily painted to
match any décor. Altec Lansing includes neutral grille cloth with
each speaker, allowing you to dye the cloth to integrate the
speaker into the surroundings. The cabinet also features internal
hanging points to facilitate permanent installation in either a
horizontal or vertical orientation.
